In a recording apparatus in which an optical mechanism sequentially irradiates a document image from a home position and guides the reflected light to an image carrier through a plurality of mirrors constituted by the optical mechanism, at least the mirrors:
A shutter mechanism is provided that covers the optical mechanism except for the optical path side with a shielding plate, and closes the open optical path side of the shielding plate when the optical mechanism is located at the home position. 1. A dustproof device for an optical system in a recording apparatus, characterized in that an optical path side of the shielding plate is opened when the optical system starts irradiating a document from a home position.
